Procurement Notes

Verify component status carefully, as this specific part number is listed as obsolete and no longer manufactured by Analog Devices Inc. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure that any replacement strategy accounts for the discontinuation status and validates technical compatibility with existing designs.

Selection Notes

Select this component for high-frequency applications requiring significant power amplification within the Ka-band spectrum. The 15 dB gain and +28 dBm P1dB make it suitable for uplink stages in satellite communication systems. Consider thermal management due to the high power density of the die format and verify interface requirements for integration into the target RF chain.

Part Context

This component belongs to the HMC-APH series of power amplifiers from Analog Devices Inc., specifically targeting wireless and RF integrated circuit applications. It is part of a family of GaAs MMICs designed for robust performance in demanding RF environments. The -SX suffix typically denotes the die configuration or packaging variant for this specific product line.

Replacement Considerations

The HMC-APH473-2-SX is officially marked as obsolete. No direct public substitute part numbers are confirmed in the provided documentation. Engineers must evaluate alternative high-power GaAs MMICs from the manufacturer's current portfolio or other vendors that meet the 37-40 GHz frequency, 1W power, and 15 dB gain specifications.
